This almost always a result of one of two things: 1> you didn’t upload the config to the correct place or the ZK that Solr uses. or 2> you still have a syntax problem in the config.
The solr.log file on the node that’s failing may have a more useful error message about what’s wrong. Also, you can try validating the XML with one of the online tools. Are you totally and absolutely sure that, for instance, you’re uploading to the correct Zookeeper? You should be able to look at the admin UI screen and see the ZK address. I’ve seen this happen when people inadvertently use the embedded ZK for one operation but not for the other. Of have the ZK_HOST environment variable pointing to some ZK ensemble that’s used when you start Solr but not when you upload files. Or… Use the admin UI>>cloud>>tree>>configs>>your_config_name to see if the solrconfig has the correct changes. I’ll often add some bogus comment in the early part of the file that I can use to make sure I’ve uploaded the correct file to the correct place. I use the "bin/solr zk upconfig” command to move files back and forth FWIW, that avoids, say putting the individual file a in the wrong directory...
